StylAir's SHL Series Heaterless Desiccant Dryers
 
StylAir SHL model dryers are heaterless, twin-tower, regenerative desiccant dryers designed to remove water vapor from compressed air and gas to a pressure dewpoint of -40°F and lower.
Heaterless (pressure-swing adsorption) dryers are preferred for their simple, reliable design and low initial cost. A continuous flow of dry air or gas is provided to eliminate moisture and contaminants found in all air and gas systems.
Standard Features
- -40°F line pressure dewpoint
- ASME Code desiccant vessels (floor-mounted models)
- NEMA 10 minute cycle, fully automatic operation
- Adjustable timer cycle for lower dewpoints (floor-mounted models)
- Fail safe operation: continuous flow on loss of power or control air
- Non-lubricated valves
- Tower pressure gauges on all models
- Gradual repressurization for long desiccant life
- ASME relief valve on outlet manifold
- Full charge of desiccant
- Heavy duty angle and channel support base (floor-mounted models)
- NEMA 4 electrical construction
- Cycle Failure Alarm (floor-mounted models)
- 120V/1Ph/60Hz operation
- On-Off switch with Power-On light (floor-mounted models)
- LED pilot lights
